While replacing my rear housing bearings and seals, I had to cut off the jam nuts. I ordered replacements but the thread pitch is too fine. The nuts I ordered are the correct part for my 2000 trailblazer but I’m wondering if my rear axle is not original to the bike. The nuts I cut off have 10 threads (fingernail counting) but the ones I ordered have 15 threads. Other than the pitch they are identical. Was there another year that had a different thread pitch? Dealer cannot answer my question.
I found the following stamped on the end of the axle. Can’t tell what numbers…Attachment 26995
I also found the part number for a 2000 TB rear axle 5133181 which looks like the number in the pic. I’m hopeless!!
